Social housing is the outcome of policymaking aimed at guaranteeing adequate living conditions for disadvantaged social groups. In Italy, in the post-war reconstruction period, buildings designed by internationally renowned architects, led to results of such high design quality that it is essential to preserve them. Nevertheless, their advanced degradation and functional obsolescence are due to being built with construction systems focused on quick completion and cost-effectiveness, as well as a lack of maintenance. Such conditions now impose performance upgrades and reuse for services and collective spaces. The paper addresses the issue of the recovery of this housing stock in the Italian context, analyzing the case of Librino (Catania). The research question is based on evidence that the lack of services and collective spaces in the suburbs leads people to move to other areas of the city for work, health, education, culture, and leisure. The proposed approach investigates the overall organization of the neighborhood, up to reuse pilots, as for the Moncada Theater, to improve the overall quality and attractiveness of the area, even with minor renovations. The theatre, which was abandoned before completion, is an example of how only housing was built or completed in residential areas designed to provide a wide range of services for citizens as a result of a funding shortfall. Reuse decisions are the result of user involvement with a view to social and cultural sustainability.

Although the size of the houses has increased in recent years, the number of house users is decreasing. The decrease in the number of users has brought forth the concept of tiny houses which use less materials, less energy, and produce less waste compared to large houses. There are several types of tiny houses, with tiny houses on wheels (THOWs) being the most preferred type. However, THOWs are subject to high-way rules because they are not permanent structures. Such rules limit the dimensions of THOWs, thus preventing the creation of necessary spaces in the interior. In this study, we exanimated mobile housing, revealed barriers to their use and dissemination, and proposed a system called POD-THOW, which could offer a solution to the space needs of THOWs. As a result, it was understood that POD-THOWs provide a solution to size restrictions, but they should be combined with lightweight constructions and sustainable energy sources to prove effective.

The European social housing stock, built since the early post-war period, now needs major energy, structural and functional upgrading. The owners, almost always public bodies, are therefore called upon to adapt these buildings to the new regulations issued by the European Community. To reduce the costs of intervention, the preferred solution is that of a complete demolition and a subsequent reconstruction by using newly supplied materials, without considering the non-sustainability and social fallout of this choice. The contribution, starting from the hypothesis that more sustainable building rehabilitation interventions are possible, analyses which social and material supply aspects must be considered, and which design strategies can be applied to achieve the objective. First, the characteristics of social buildings in their historical evolution are summarized to understand their value in a broader non-economic sense. Subsequently, the requirements for a sustainable renovation of the existing social dwellings are analysed, and three, out of many other, design strategies are proposed. A case study is then presented and the application of the three strategies done through three Master thesis works is described. In conclusion, the results of the application of the strategies to the case study is analysed to assess whether it is possible to intervene on existing social housing complexes to achieve better results with a more sustainability-oriented perspective.

Decolonization process in India involved a range of political, economic, and social changes aimed at dismantling the colonial system and building a new, independent nation. One of the most significant challenges India faced during the decolonization process was the issue of partition. The partition of India in 1947 led to the creation of two separate countries—India and Pakistan—and resulted in widespread violence and displacement. Millions of people were forced to migrate across the newly formed borders, resulting in one of the largest mass migrations in human history which created huge demand for housing. The methodology adopted for this research is based on qualitative analysis and the data source for this study are government reports, research articles, books and newspaper. Further, it examines four case studies of social housing projects designed to provide sustainable and livable solutions for low-income families in different regions of India, including Aranya Community Housing, Incremental Housing in Belapur, ATIRA Staff Housing in Ahmadabad, and CIDCO Housing in Parsik Hill in Navi Mumbai. At the core of the article lies an investigation into the dynamic nature of architecture in the aftermath of independence, coupled with a detailed examination of four distinct social housing ventures. The social housing studies demonstrate innovative and flexible approaches to social housing, with a focus on community building, energy efficiency, and social amenities. The projects have been successful in providing access to affordable and sustainable housing for low-income families in different regions of India. The case studies highlight the importance of a community-centered approach to social housing, emphasizing the need for shared spaces and amenities. The article discusses the challenges and opportunities of implementing sustainable and livable social housing solutions in India.

This article presents the most widely used methodologies to measure, analyse and assess the state of the building stock and the life conditions of people living in vulnerable neighbourhoods, in an attempt to identify limitations and opportunities within the design of more suitable instruments that will allow us to identify residential communities in a vulnerable situation, residential exclusion or at difficulty to access rehabilitation subsidies or allowances. The methodology adopted is based on the obtention of a first vulnerability index constructed from quantitative data that allows us to focus on the most vulnerable areas of the cities under study. Later, it is complemented with qualitative analysis, interviews to technical officers, entities’ representatives, and site visits and observations. The main obtained results consist of different methodological approaches and analytic and geospatial measurements of the residential vulnerability in the cities of Barcelona and Bilbao: from quantitative large-scale multicriterial analysis, geospatial analysis on specific aspects, to small-scale qualitative study cases, fieldwork and interviews to different actors. In conclusion, by applying those different methodologies in the same specific areas, we were able to determine how data disaggregation and specificity in relation to urban and building form and location provide relevant differential results that help to qualify certain patterns that can be detected but not explained by quantitative larger-scale integrative analysis. Besides, the qualitative information provided by key local agents of different networks was crucial to explain and understand the nature of geographical and time-changing patterns of residential vulnerability.

The topic of indicators as measurers of the effectiveness of urban and housing transformations strongly re-emerge because of the performance approach the funding of the National Recovery and Resilience Plan (NRRP) is based on. Within the NRRP specific programmes, the issue of performance measurability of interventions was managed with the application of different indicators and application methods. The research group had the opportunity to work on the construction of a system of indicators for a national urban regeneration programme, financed within the NRRP. This paper describes the research aimed at the definition of the indicators for evaluating the design proposals applied to the NRRP financed program called PINQuA (Innovative Programme for Housing Quality). The proposed system of indicators proved useful to promote an objective reading of the interventions and to encourage, in the design proposals application, the response to housing quality criteria aimed, among other issues, at improving the cultural condition of the contexts.

Social housing in Spain has its origin in the first Cheap Houses Law that was promulgated in 1911, trying to provide a solution to a housing need for the working class who flocked to the cities in waves of migration from rural areas. Since then, legislative initiatives have been taking place to mitigate the housing problem. Each one of them was contributing elements that presumably contributed to the hygiene and habitability of the house without forgetting the economic conditions. At the moment, in Spain there is a large real estate park inherited from these initiatives. In many cases, these are neighborhoods that currently show notable energy and social vulnerability. Aware of the need to adapt these homes to the regulatory requirements related to energy efficiency, comfort and the physical and technical characteristics of the construction, the Research Centers are developing multiple investigations aimed at favoring the adaptability of homes and improving the quality of life of its inhabitants. This article takes a tour of the evolution that social housing has had during the 20th century in Spain and the current state of research aimed at adapting it to the new energy, habitability and sustainability requirements.

The aim of the research is the laboratory study of a durable concrete, according to UNI-EN 206-1 and 11104, comparing four types of concrete by varying the type of binder to highlight some aspects of durability. For each type of concrete, to graph the correlations between: W/C ratio - resistance; cement dosage - strength; days of ripening-resistance; three mixes were packaged by varying the W/C ratio and the cement dosage. Three durable concretes were then designed, by way of example, with resistance class C30/37, exposure class XS1, workability class S5, maximum diameter 20 mm, by varying the type of binder to enhance some aspects of durability: - Type 1) With Portland II-A-LL 32.5 R cement - Type 2) With Portland II-A-LL 32.5 R cement + 11% silica fume - Type 3) With Portland II-A-LL 32.5 R cement + 22% fly ash. A cost analysis was then conducted for the concretes type 1), 2), 3), to highlight the incidence of additions in the concrete, and the benefits in terms of mechanical resistance to compression.

The invention of reinforced concrete in the second half of the XIX century brought about a real revolution in buildings design and construction. Thanks to this new construction technique, the first skyscrapers were built at the beginning of the last century, and within a few years large urban agglomerations sprang up. The invention of reinforced concrete thus marks the beginning of the dramatic conflict between construction and environmental protection, which has led to the dramatic effects of climate change, pollution and depletion of natural resources. The use of this material also allowed the birth and spread of the Modern Movement, which has left us with an enormous architectural heritage spread on a global scale. The value of the architecture of the Modern Movement is not always recognized as it should be, probably because it belongs to a too recent past. The article highlights the attention paid to the search for passive systems to control comfort conditions inside buildings by the architects of the Modern Movement, who anticipated and addressed the issue of energy saving and sustainable building.
